My AC H3 stopped driving on the right side over about a 1 hour period of time while I was grading. It would only go in a circle to the right. I pulled the clutch from the right final drive housing which had a lot of water and grease in it. All of the teeth on the driving discs (fiber) were gone and the hub spins but is not tight (has wobble when wiggled). Is this just a pilot bearing gone bad, or do I have other problems that would cause it to stop driving on the right side? I must have a worn seal on the drive shaft too with all the grease in the housing. I will replace the drive shaft bearings/seal, the pilot bearing on the clutch and the fiber discs. Anything else? Thanks

POST SOME PICS AND WE MAY BE ABLE TO HELP. FOR ONE THING I DID ON BOTH OF MY STEERING CLUTCHES ON HD4 WAS REPLACE WITH THE NEW BI-METALIC TYPE. CAN PURCHASE WHAT YOU NEED FROM GENERAL TRACTOR PARTS IN IDAHO. ALSO CAN GET HUB PARTS FROM BLOUNT PARTS IN GEORGIA.

Check bearings and seal on the driven side also as these support the clutch drum.

Thanks for the responses. I replaced the drive shaft bearings and seals. The pinion shaft seems solid but there are other bearings for the final drive gear and sprocket that I can't get to without removing the track. So, I think I will put the clutch back in with the new pilot bearing and discs and hope for the best.
